RE: T-Shirt size
Re: [scrumdevelopment] Here's aThoughtHi Danny,Note that T-shirt size estimates (and story points or Ideal team Days for that matter) are not synonymous with duration. Rather they are relative estimates of overall size of the item. To determine duration, you need to also know the team's velocity (number of shirt sizes or story points the team can complete in a sprint). These size estimates are also idiosyncratic to the team so they cannot be compared between teams (unless you take some specific steps to align the teams' estimating). In scrum we estimate size and derive duration, which is fundamentally different than the traditional way of directly estimating duration. For a detailed exposition about estimating this way, you might want to look at Mike Cohn's book "Agile Estimating and Planning."-Jeff

Subject: T-Shirt size
Is there a definition for a T-shirt size (i.e. M for 4 days, L for 8 days, etc.) so when going over a backlog of another team, the "language" will be he same?
